OK so xslt 1 then, you didn't say if x:node-set() is available.

Also, simply running two passes, i.e. a preparatory pass before the final rendering pass, is sometimes reasonable. Such a preparatory pass can also be useful for other purposes, albeit at the cost of making your production pipeline more complex as well simply being impractical in certain architectures. But there's nothing inherently wrong with doing this.

XSLT 1.0 is really optimized for transformations that render data that is already fairly well organized for the purpose, whatever that may be. Of course, this is a circular definition ("it's good at what it's good at"), but given that in the early days, "documentary data" usually met this description when the purpose was display, and "structured data" was often served up by a database that could handle the necessary (re)organization, it wasn't an Achilles' heel, just a weakness. The grouping-and-sorting-together problem is really the use case that demonstrates that more power is often needed even in applications that are otherwise about as plain and straightforward as they come.
